What will be an ideal response?
(a) Consider that two infinitely long parallel edge dislocations are viewed on a simple two dimensional x?y diagram, such as Fig. 4.37. This first of these dislocations is located at x = 0, y = 0 and is positive. Its slip plane is horizontal and this contains the x?axis. The other dislocation is negative and also lies in a horizontal slip plane separated from that of the first dislocation by a vertical distance (y) of 10b, where b is the Burgers vector for both dislocations. Now assume the first dislocation is fixed in place, and the second can move parallel to the x?axis. With the aid of a computer, plot ??, the x component of the force (per unit length) between the dislocations, as function of x from x = ?50 nm to x = +50 nm. Let u =86 Gpa, b = 0.248 nm, and v =0.3.
(b) Discuss the significance of the variation of Fx with distance as the mobile dislocation moves from x= - ? to x= +?.
